Merrill Lynch's Scott Craig said there's a good chance Deutsche Telecom will announce the iPhone's arrival next week

T-Mobile is the last of the four major U.S. carriers to not offer Apple's iPhone, but that may change at next week's analysts day.

According to Merrill Lynch's Scott Craig, there's a good chance Deutsche Telecom will announce the iPhone's arrival to T-Mobile during analysts day on December 6 and 7.

It's very possible that this could be the case, since T-Mobile recently spread its high-speed HSPA+ network (which is compatible with the iPhone) to 10 new metropolitan areas.

A deal between Apple and T-Mobile could be beneficial for both, as Apple would have its device available on all four major carriers and T-Mobile would likely see a sales boost.

However, just last week, T-Mobile USA COO Jim Alling said that it'd be nice to carry the iPhone, but it just isn't worth it.

Jim Alling, COO of T-Mobile USA, said, "Make no mistake about it: We would love to carry the iPhone. However, we want the economies to be right for us."

Apparently, T-Mobile doesn't want to be stuck in the same position as Sprint. When Sprint took on the iPhone 4S for the first time in September 2011, the deal cost $15.5 billion. Sprint said its iPhone operations won't be profitable until 2015.

T-Mobile recently blamed its branded net contract customer losses during Q3 2012 on the iPhone 5, since it's available at Verizon, AT&T and Sprint.
